"Impressive and dramatic, the White Cliffs of Dover keep watch as a citadel over the southern entrance into the Strait of Dover, which separates England from France. These towering escarpments, stretching 10 miles (16 km) along the coast, not only once guarded England from its enemies but, more importantly, they now give tribute to the global Flood as described in Genesis 6–9.

Many secular geologists claim that these chalk beds speak of an old earth since they believe chalk formed slowly and progressively over millions of years. However, when we interpret the evidence from a biblical perspective, we see that there is an explanation for the formation of these chalk beds that aligns with the biblical timescale of thousands of years. The main cause of these beds is the catastrophic, worldwide Flood.

The white chalk of these cliffs is composed almost entirely of calcium carbonate. This calcium carbonate, a very pure type of limestone, consists of billions of microorganisms that today live in the upper 300–600 feet (90–180 m) of the open seas. When these microorganisms die, their calcium-rich shells accumulate on the bottom of the ocean floor. These shells cover about one-quarter of the surface of the earth today.

The measured rate of chalk accumulation today seems to demonstrate that these chalk beds could not have formed quickly. Evolutionists claim that these chalk beds were formed around 70 to 100 million years ago, during the “Cretaceous period,” when the southern portion of England was submerged by a shallow tropical sea.

However, under the right conditions, rapid production and accumulation of these microorganisms on the ocean floor is possible. These conditions include turbulent waters, high winds, decaying fish, increased temperature and nutrients from volcanic waters and other sources. With catastrophic volcanic activity warming the oceans and releasing large amounts of CO₂, and with the torrential rains and the churning and mixing of fresh and salt waters, the Flood of Noah’s day produced the right conditions for a “blooming” production of micro-organisms and the chalk’s rapid accumulation.

Thus, the White Cliffs of Dover confirm the biblical account of a global Flood just over 4,000 years ago. The evidence is apparent when viewed through a biblical perspective."  Full text:  Creation Road Trip: White Cliffs of Dover http://www.answersingenesis.org/articles/am/v1/n1/creation-road-trip-more
